In Geometric landscape XXVIII, Costa balances the fluid unpredictability of watercolor with the deliberate, opaque boundaries of acrylic paint. This interplay creates a layered topography where mountains, valleys, or foliage are reimagined as a series of interlocking planes. By utilizing a vertical orientation, the artist emphasizes a sense of depth and ascension, inviting the eye to climb through the stratified layers of the composition as if navigating a physical terrain built from pure color.

The work functions as both a landscape and a technical illustration of space. Rather than mimicking the literal curves of nature, Costa uses sharp angles and distinct segments to evoke the spirit of the outdoors. The result is a grounded exploration of how light and form occupy the environment, rendered with a clarity that honors the raw geometry found within the wild.
